The power the vinvention resides iny certain novel ifea-I would be used after the wells have produced tures of `construction and iin the combina their flush production. This is the advantion and arrangement of parts/'as wil'lihere 15 tage of my adjustable stroke power, as the after inorel'ulfly bev described and' claimed Stroke can easily be adjusted an inch at a Figure l-is atop VViewy of myeccentricV time as the wells get smaller and it is desired put together so that there would be noto have a shorter stroke. I strokeonthe shackle line,'as the' shaft is Another improvement on this power is to centered" with outeredge of the eccentric1 as shown in Figure 1, but set to give the maximum throw or stroke on the shackle line. z

Figure 3 is a sectional view showing how the two eccentric rings in Figures 1 and 2 are adjustably held together by bolts, and how the shackle line support lrim runs ina bath of oil. Y

Figure 4 is a part sectional view of the usual band wheel that turns the hub and eccentric, such giving the rim that the shackle lines are attached to the horizontal movement that is carried to the different jacks at the wells. Y

Figure 1 shows a top view of the shaft 1, hub 2, inner ring 3, and outer ring 4. The way eccentric 4 is set on inner ring 3 it does not give the shackle lines any stroke, and this view isnot practical, but simply used to illustrate the possibilities of using two adjustable accentrics.

Figure 2 shows a top view as Figure 1, except that the outer ring 4 is just turned half way around on 3 and gives the maximum stroke on the shackle line. Now to get half the stroke on the shackle lines shown in Figure 2, just turn the outer ring 4' one-quarter around on 3. If desired to shorten stroke one-twelfth on Figure 2, just turn the outer `ring 4 one hole on the inner ring 3, and so on, to getany length stroke desired. The holes, 16, are spaced the same distance apart on both 3 and 4 and canvbe spaced closer together for liner adjustment of stroke on shackle line if desired.

Figure 3 vis a sectional view showing the outside portion of inner ring 3 and part' of the outer .ring 4, and how 3 and 4 are adjustablyheld together as one eccentric by means of bolts 14 and nuts 15. It also shows how the oil pan 6 is held securely to the outer ring 4 by means of bolts 11, and oil is kept from leaking out of the pan by use of the pad 10. 5 indicates the shackle line support which has a bearing. on the outer ring.4 and the bearing surfaces of 4 and 5 run in a bath of oil,-5 may be held on 4 -in any desired manner. 12 shows the shackle hook and 13 shows means for holding 12 to rim- 5. f

In Figure 4 the shaft 1 is shown, 2 shows the hub, 9 .and 17 show adjustable spokes which hold the rim of the band wheel 7 the angle 8 is a stiff brace for the band wheel. Bolts 18 hold the inside ring 3 to the hub 2. Bolts 14 hold outer ring 4 secure to 3. Bolts 11 hold the oil pan 6 secure to the outer ring 4, and 5 indicates the shackle line support which runs in a bath of oil. 12 shows the shackle line attachment, 19 shows bearing plate, and 20 indicates the .usual foundation.

What I' claim and desire to secure by Letters Patent is:

1. A double eccentric consisting of a hub having an outwardly extending flange, an inner .ring having an inwardly extending flange bolted to said former liange and also having an outwardly extendinor portion, an outer ring having an inwardly extending portion overlapping the former portion and means circumposed about the outerperiphery of the outer ring. v

2. An adjustable eccentric comprised of a hub having an outwardly extending fiange, an inner ring having a flange riding on said outwardly extending flange, an outer ring having a flange riding on said inner ring, rim means encircling said outer ring, means for holding the inner and the outer rings together, and means for holding the inner ring and the hub flange together.

3. An adjustable eccentric consisting of a hub having a seat therein, an inner eccentric ring having a circular projection snugly riding in said seat, said inner ring lhaving a groove or seat along its outer edge, an outer ring having a circular projection fitting in said-groove or seat, said outer ring having a groove along its outer periphery and circular means sliding therein.

4. An adjustable eccentric vcomprised of a vertical hub, an inner ring having a circular series of holes along its outer edge, means for fastening the inner yring to the hub, an outer ring having a groove along its outer edge and a series of holes along its inner edge in alignment with Ysaid first mentioned holes, means in said holes for holding the outer ring upon the inner ring, a rim mounted in said groove and `circular means bolted to said outer ring and extending outwardly and upwardly and then inwardly to a point adj acent the rim whereby an oil chamber is formed.

In testimony whereof I affix my signature.
